Mystery Belt (Limited Quantities)

Order the Groove Belt size that matches your pant waist size. Sizes are designed to fit true to waist measurements.

Pant size 30–32 → Size S (Waist 28”–32”)

Pant size 33–34 → Size M (Waist 33”–36”)

Pant size 35–36 → Size M (Waist 33”–36”)

Pant size 37–38 → Size L (Waist 37”–40”)

If you’re between sizes (for example, a 32 or 36), it’s best to size up for the most comfortable fit and adjust using the tail slack. You can cut off any extra webbing you think is too long. Check out this video on how.

Groove Belts are true to size but include a few extra inches of slack to fine-tune your fit without feeling tight.

Yes, our OG Groove Belt is available up to XXL, which comfortably fits waist sizes from 50–60+ inches.
